To all whom, it may concern:

Beitknown that 1, JOHN RICHARD EDWARD BYRNE, residing at Tilden, in the county of McMnllen and State of Texas, have invented a new and useful Improvement in \Vindmills, of which the following is a specification.

My invention is an improvement in windmills, and relates particularly to the means for supporting the wheel and operating shafts and the means for throwing the wheel-controlling devices into and out of engagement with the wheel and to the construction of the wheel; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation, parts being broken away and others shown in section, of a windmill embodying my invention. Fig. 2 is a front view thereof, parts being broken away. Fig. 3 is a side view from the opposite side from Fig. 1. Fig. 4 is a rear elevation of a mill. Fig. 5 isatop plan view thereof. Fig. 6 is a detail perspective view of the brake and its operating devices. Fig. 7 is a detail view of one of the blades of the wheel; and Fig. 8 is a front elevation of the wheel, parts being removed.

In carrying out my invention I provide at the head of the mast a a frame comprising the base-plate A, having a bracket B, supporting the bearing B of the wheel-shaft, and a bracket 0, supporting the bearing 0 of the crank-shaft, the bearings B and 0 being at right angles to each other and horizontal and the bearing B being to one side of the center of the mast, as will be understood from Fig. 5. The wheel-shaft D is jourualed in the bearing 3 and extends at its inner end beyond said bearing, as shown at D, and is supported at its inner extremity in a seat or bearing 0 formed in the bearing 0 in alinement with the bearing B, as shown in Figs. 1 and 5.

The shaft D may be held from outward movement by the pinion E, secured on said shaft at the inner end of the bearing B, or shoulders or collars may be provided for such purpose, as desired. The pinion E meshes with the gear F on the crank-shaft F, which journals in the bearing 0, so the movements of the shaft D may be transmitted to the wheel F, which bears the crank-pin F from which extends the pitman F for driving the pumping-rod F, a swinging guide-rod F being pro vided, as shown in Figs. 1 and 3.

The wheel G has a hub G, fixed on the shaft I), and is provided at its inner side with a rearwardly-projectiug annular rail H for engagement by the brake presently described. As shown, the rail H is a flange on a center plate H, which is preferably integral with the hub G and to the inner side of which are secured the rear arms I of the wheel, such arms being bolted to the plate H and seated at their inner ends in a groove 0r socket at I, so the arms I will be heldin place in case their securing-bolts should get loose. The hub G is also provided at its outer end with a center plate J, to which the outer arms J of the wheel are secured, and this plate J is provided adjacent to the hub with openings or sockets J to receive the inwardly-bent ends J of the arms J.

The fan or blade K may be of sheet-iron cut in a U shape and having lips or lugs K and K out and bent as shown in Fig. 7. These lugs K K may extend at an angle to the fanblade and be perforated for the rivets by which the blades are secured to the rings K such rings passing through the openings K produced in forming the lugs K K By arranging the shaft of the wheel to one side of the mast ait will be evident from Fig. 5 that in case of unusual wind-pressure the wheel will be blown out of the wind.

On the plate A, I provide a tubular bearing L for the shaft L, to which are fixed the leverarms M, M, and M The lever-arm M is Weighted by the weight M which may be adjusted along the arm and secured in any desired position by the set-screw M. An oper ating chain or line h 5 connects With the arm M and leads over a guide-pulley M and thence down through the mast and may extend in convenient reach of the operator. The arm M is connected by a pitman N with the lever vane-bar O, the connection being preferably by the aid of a T-shaped bracket 0, riveted to the lower vane-bar, which is pivoted at 0 The bracket 0 has arms 0 and 0 extending at right angles to the vane-bar O. The arm 0 connects with the pitman N, and the arm IOC O is connected with a rod P, which connects with the lower end of the swinging brakearm Q.

The brake-arm Q has its upper arm bifurcated at Q to fit on opposite sides of the hearing B, to which it is pivoted at Q so the lower end of the brake-barQ mayswing to and from the wheel. At its lower end the brakebar Q has a forwardly-projecting arm Q which supports the shoe Q, which bears against the flange H of the wheel.

In connecting the rod P with the brake-bar Q, I prefer to pass the said rod through an opening Q in the bar and secure it by a nut P in front of the bar and a nut P in rear of and slightly separated from the said bar Q, as shown in Figs. 1, 5, and 6. A spring P bears between the nut P and the bar Q and operates to cushion the pressure of the brake against the wheel. Manifestly the nut P can be set to vary this cushioning action.

The operation of the construction is as follows: In the normal position of the parts, with the weighted end of the lever M down, the vane holds the wheel to the wind and the brake-shoe Q will rest clear of its track on the wheel. If the wind blows too hard, the wheel by its relative position to the mast will blow out of the wind and around toward the vane, causing the latter to stand at a different position with respect to the mast and causing the arm O to pull on link N,which in turn will rock the lever M raising the weighted arm or bar M. At the same time the arm O on the vanebar will thrust the rod P forward, forcing the brake-shoe Q against the wheel to such an extent as to prevent it from running too fast. When the undue wind-pressure has ceased, the relative position and action of the weightbar M, through the levers, links, and rods, will throw the mill back to its normal position or into the. wind.

Should the operator wish to shut the mill off, he will pull on the line M which will so rock the lever M as to cause it to operate the lower vane-bar to throw it from a right angle to the plane of the wheel and to thrust the rod P forward and brake the wheel to such an ex tent as to slow it down or stop it, as may be desired, in which position it may be retained by suitably securing the line l The guiding-arm F is pivoted to an arm F which extends from the bearing B, and being short can be made of great strength and rigidity.

It will be understood that the bevel-gears E and F can be adjusted along their shafts to take up the wear in both the gears and the boxes of the shafts, thus saving the expense of rebabhitting or reboxing the bearings. This may be accomplished by fastening the gears to their shafts by keys or feathers, so they can be moved along their shafts by sim ply loosening the feathers and forcing the gears to the desired positions, as will be understood from Fig. 5.

The all-lever shut-off is an important feature, as it will not be affected by any ordinary wear, and the weight which adjusts the brake clear of the wheel can be conveniently adjusted to any desired extent, and such weight; also operates to hold the wheel at a right angle to the vane.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A windmill comprising the main frame having brackets supporting bearings at right angles to each other, the wheel-shaft in one of said bearings, a pinion on said shaft, the crank-shaft in the other bearing and having a gear meshed with the pinion of the wheelshaft, the wheel having a track or bearing on its rearside, the brake-arm havinga shoe movable into and out of contact with said rail or hearing, the rod connected with said brakearm, the vane-bar having an arm connected with said rod, a lever-arm connected with the said vane-bar, the weighted lever and the operating-lever having a chain or line leading to the operator, substantially as set forth.

2. A windmill comprising the main frame having brackets supporting bearings at right angles to each other, the wheels, the wheelshaft in one of said bearings, the crank-shaft in the other bearing, gearing bet-ween the two shafts, the vane-bar pivoted to the main frame, the brake operating upon the wheel, the weighted lever connected with the vanebar, and connections between the brake and the Vane-bar, substantially as set forth.

3. In a windmill, the combination of the main frame having a hearing B for the wheelshaft and a bearing C for the crank-shaft and having the bearing (3 provided at its side with a bearing 0 in alinement with the hearing B, the wheel-shaft journaled in the hearing B and having its extremity supported in the bearing 0 the wheel and the pinion E on the wheel-shaft, the crank-shaft having a gear F meshed with the pinion E, the brake for the wheel, and the lever mechanism for setting the brake, substantially as set forth.
